Mitsubishi Chemical develops GaN substrate for development of GaN epitaxial wafers
On May 7th, Mitsubishi Chemical actively expanded the white LED business and established a link to strengthen the business of GaN. Mitsubishi Chemical's GaN substrate, in addition to the company's own white light-emitting diode (LED) bulbs, is intended to open up applications to anticipate future increases in demand for ultra-small to large-scale high-efficiency green laser diodes (LD) ), and the use of electronic equipment such as power transistors for hybrid electric vehicles (HV) and electric vehicles (EV). In particular, the use of NTT Advanced Technology (NTT-AT), the company officially produces the Epitaxial Wafer, and uses the company's proprietary gallium nitride substrate as the base substrate. Develop higher performance wafers. The epitaxial wafer is made of silicon or sapphire as a base substrate, and a film-like crystal is grown thereon. Therefore, it is used as a power conversion device such as a power amplifier or a current converter for a mobile phone base station. However, for applications requiring high withstand voltage such as vehicles, it is suitable to use a gallium nitride epitaxial wafer based on a gallium nitride substrate. For this reason, the gallium nitride substrate produced by the company has been actively invested in the development of epitaxial wafers, and has been sought to expand the use of electronic devices. At present, the company's Tsukuba Plant (Niujiu City, Ibaraki Prefecture) is producing a 2-inch c-plane substrate, which has been increasing from 100 pieces per month to 500 pieces since March 2010. It is scheduled to be in existence in 2010, with luminous efficiency. The product is 3 times the 2 inch m-plane substrate, and the production system with a monthly output of 2,000 pieces is established. The company is also developing a new method of "liquid phase deposition" that can reduce the price of gallium nitride substrates, which can also correspond to a 4-inch large-diameter product. The main function of the MPPT Solar Controller is to realize maximum power point tracking (MPPT) in the solar power generation system to improve the energy utilization efficiency of solar panels. It is an advanced charge controller that can adjust the output voltage and current of the Solar Panel in real-time to keep the solar panel operating at the maximum power output point. 10 amp mppt solar charge controller, solar charge controller 10 amp, 36v mppt solar charge controller, dc dc mppt charger, lithium ion solar charge controller Ningbo Autrends International Trade Co., Ltd. , https://www.aitsolarpanels.com
Main effect:
Maximum power point tracking: MPPT Solar Controller can accurately calculate the maximum power output point of the solar panel by monitoring the voltage and current of the solar panel in real-time and according to the characteristics of the solar panel. It then adjusts the panel's output voltage and current to keep it operating at its maximum power output point, maximizing the solar panel's energy conversion efficiency.
High energy utilization rate: MPPT Solar Controller's maximum power point tracking function can ensure that the solar panel is always operating in the best working condition, making full use of solar energy, thereby improving the energy utilization rate of the photovoltaic power generation system.
Charge control: In addition to achieving maximum power point tracking, MPPT Solar Controller also has a charge control function to protect the battery from overcharge and over-discharge damage.
Differences from other charge controllers:
Maximum power point tracking function: MPPT Solar Controller is a charge controller specially used in solar power generation systems. The biggest difference is that it has a maximum power point tracking function, which is used to improve the energy conversion efficiency of solar panels. Other charge controllers may not have this unique feature.
Energy efficiency: MPPT Solar Controller can improve the energy efficiency of solar panels through maximum power point tracking technology. Other charge controllers may only be able to charge in a fixed manner and cannot achieve maximum power point tracking.
Application scenarios: MPPT Solar Controller is mainly used in solar power generation systems, while other charge controllers may be suitable for different types of energy generation systems, such as wind power, hydropower, etc.
Overall, the main role of the MPPT Solar Controller is to achieve maximum power point tracking, improve the energy conversion efficiency of the solar panel, and protect the battery from overcharge and over-discharge damage. Compared with other charge controllers, it has unique advantages in energy utilization efficiency and maximum power point tracking and is suitable for applications in solar power generation systems.
